TOY BLOCKS.-

Specification of Letters Patent.

Patented July 13, 1909.

Application filed February 8, 1909. Serial No. 476,731.

' are fully set forth in the following s ecification, and the structure is illustratec in the accompanying drawings, in which- Figure 1 shows a trussed bridge formed of the blocks composing the set; Fig. 2 is a detail longitudinal vertical section thereof; Figs. 3, 4, 5 and6 are erspectives of the: various elements. of which the set is formed.

The setof blocks comprises a lurality of bars 10 otuniform length and eac having an aperture 11, 12, adjacent each of its ends; a p urality of rods 13 com lementary in form to the a ertures 11 an 12; a plurality of flooring oards 14, of awidth'less than the length of the rods 13, and corresponding in length to the distance between the apertures of each of the bars 10; and a plurality of pedestal blocks 15, each having an aperture 16, adapted to receive the rods 13. These elements may be assembled in various ways. As shown in Fig. 1, they are assembled to form a section of a trussed bridge, having two side frames composed of the bars 10, arranged to form a lower stringer 17, and an upper stringer 18 for each frame, and diagonals uniting both ends of each element of the lower stringer with one end of each element of the upper stringer; the elements of each frame an the two *frames being secured to gether by means of the rods 13 assing through the apertures 1 1, 12, of the el dments 10. The structure thus formed is sup orted on four of the pedestal blocks 15 fitte( upon the ends of the two lower end rods 13. The structure is also provided with a flooring formed of the flooring boards 14, the ends of which are chamfcred, as shown at 19, 20, to fit upon the cross rods 13. The number of elements of each set may be varied.

I claim as my invention- 1. In toy blocks, in'combination, a trussed structure com arising a plurality of bars of uniform length each havin a round aperture adjacent each of its on s, a plurality of round rods adapted to fit within such apertures and of suchlength that a plurality of bars may be applied thereto and spaced apart, and a plurality of flooring boards corresponding in length to the distance between 1 centers of the a ertures of the bars and having their ends 0 iamfered to engage the rods whereby longitudinal displacement of the flooring boards in the trussed structure is prevented.

2. In toy blocks, in combination, a trussed structure com arising a plurality of bars of uniform length each having a round aperture adjacent each of its ends, a plurality of round rods adapted to fit within such apertures and of such length that a plurality of bars ma be a )lied thereto and spaced apart, and a p irality of pedestal blocks apertured to receive the rods.

3. In a set of toy blocks, in combination, a

lurality of bars of uniform length each havmg a round aperture adjacent each of its ends, a plurality of round rods adapted to fit within such apertures and of such length that a plurality of bars may be applied thereto and spaced apart, a plurality of flooring boards corresponding in length to the distance between centers of the apertures of the bars and having their ends chamfered to engage the rods, and a plurality of pedestal blocks apertured to receive the rods.
